ios - 从UIActivityViewController调用时，选择收件人后WhatsApp卡住

Question

我正在使用UIActivityViewController共享我的iOS应用。

从选项列表中选择WhatsApp时，它将带我到正确的屏幕。我可以四处走动，所有按钮都可以使用。

但是，一旦我选择了收件人，WhatsApp就会冻结。

有人知道这是怎么回事吗？有人遇到过此错误吗？

编辑(已添加代码)

这是我用来调用UIActivityViewController的代码:

- (void) sharePressed:(UIBarButtonItem *)sender {

NSString* shareText = @"Hello World!";

UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:@[shareText] applicationActivities:nil];

[self presentViewController:controller animated:YES completion:nil];


NSLog(@"This method ran: sharePressed");
}

它是最基本的。它适用于除WhatsApp之外的所有内容。

试试这个代码

- (IBAction)shareButton:(UIBarButtonItem *)sender
{
    NSString *textToShare = @"Look at this awesome website for aspiring iOS Developers!";
    NSURL *myWebsite = [NSURL URLWithString:@"http://www.codingexplorer.com/"];

    NSArray *objectsToShare = @[textToShare, myWebsite];

    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

    NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                                   UIActivityTypePrint,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypePostToFlickr,
                                   UIActivityTypePostToVimeo];

    activityVC.excludedActivityTypes = excludeActivities;

    [self presentViewController:activityVC animated:YES completion:nil];
}
